Software Defined Radio's use software to replace the traditional
components found in hardware defined radios.

Over the past 10 years, the cost of radio front ends for computers has
declined to the point where anyone with a computer can afford a simple
radio front end. The flexibility of software combined with lower cost
radio hardware led to an explosion of interest in SDR.

The SDR devroom has talks about frameworks, research projects,
applications, hardware, and tools. This is the place for Open Source SDR
developers to meet, exchange ideas, and start working together to
improve the state of Open Source and SDR.
